This invention has reference to root construction, and aims to provide a flexible metallic flashing lath, designed for use in place of the usual wooden flashing lath now commonly employed for securing flashing.

The primary object of the invention is to provide a flexible lath which may be positioned by bending the same around chimneys or other onset portions of flre walls of roofs, eliminating the necessity of cutting the flashing lath to flt a particular roof or wall irregularity.

Another important object of the invention is to provide a flexible flashing lath which may be stamped from a length of sheet metal by a single stamping operation, thereby rendering the lath exceptionally cheap to manufacture.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a plan view of the blank from which the flashing lath is constructed.

Figure 2 is a perspective view of the lath.

Figure 3 is a horizontal sectional view through the connected ends of adjacent laths.

Figure 4 is a vertical sectional view through a wall and roof illustrating the application of the 35 lath.

Figure 5 is a horizontal sectional view through a wall and chimney showing the lath as bent around the chimney.

Referring to the drawing in detail, the lath comprises an outer casing or body portion indicated generally by the reference character 5, and as shown this casing is formed by stamping it from a length of sheet metal material, the construction of the blank formed by the stamping operation, including a main section 6, and a plurality of laterally extended tongues '7, the tongues 7 being disposed opposite to each other on opposite sides of the main section 6.

These tongues are of lengths so that when they are folded over the core of the lath, the free ends oi the tongues will be disposed in close relation with each other to clamp the core.

Due to this construction, it will be seen that in the stamping of the casing, waste of the sheet metal material from which the casing is formed will be reduced to a minimum.

to be fitted in one end of the adjacent lath, thereby securing the adjacent laths together in the formation of a continuous flashing securing lath.

The core of the lath is constructed of lengths of tar or other composition paper indicated by the reference character 9, the lengths of paper 9 being superposed as shown by Figure 2 of the drawing, and held in position by bending the tongues '7 over the lengths of paper 9.

The core is of a length to extend an appreciable distance over the extension 8, so that when the flexible lath is bent around an irregularity of a wall or roof construction, the lengths of composition paper may slide and automatically adjust themselves to the irregularities.

The person applying the flashing lath will trim off that portion of the core which overlies the extension 8, so that the ends of the core will be flush with the outer edges of the tongues '7 at the ends of the main section 6.

Openings indicated by the reference character 10 are provided in the main section 6, and are so arranged that securing nails driven through the openings to secure the flexible flashing lath, will pass through the lengths of asphalt paper, and through the overlying tongues '7, securing the tongues and core, against movement.

In the use of the device, the lath forming the subject matter of this invention, is used in place of the usual wooden flashing lath, and is positioned along the roof flashing so that the upper edge of the lath is flush with the upper edge of the flashing, the lath being secured by means of securing nails 11.

It will of course be understood that after the lath has been positioned, a layer of roofing cement is placed along the upper edge of the lath, sealing the connection between the lath, flashing and wall.

Having thus described the invention what is claimed is:

A flashing securing lath comprising an elongated casing embodying a length of sheet metal material having cut out portions in the side edges thereof, said out out portions deflning tongues extended laterally from the opposite edges of the casing, a core embodying dependent layers of composition paper material arranged in strips, and free to move one with respect to the other, said tongues being extended over the core, securing the core in the casing, and means for securing the lath in position.

The tongues 7 at one end of the casing 5, are

spaced from the end of the main section, as clearly shown by Figure 1 of the drawing, providing 69 an extension 8 at one end of the main section,
